You obviously didn't get rid of all the republicans, because the every day government worker is still a republican, working for a republic. All the guys who still make everything happen, who run the warehouse, who run the bank, who deliver your mail, etc etc are still there. Terran's government may have failed to do anything but maintain a city state, but it hasn't collapsed.
No, the republican officials are gone. They fled, along with many of the Chateau's people. There's no republic. No voting except where Hireshmont wants it, no republican titles, no republican laws, and oaths to the Bloodstars have been received by the lower-ranking officials.
They aren't republicans, and there isn't a republic. There's a game label (which, AFAIK, actually does absolutely nothing– republic and theocracy have the same game effects, don't they?) which is defunct because the realm is in fact, in every way, a theocracy.
You can't claim that just because the game has the label "theocracy" that we're wrong in RPing OUR NPCs as theocratic.
